Temperature controller air outlet

Abstract

Control of temperature of air efflux from an air outlet is by control of the oscillation of a fluidic oscillator. Directionality of efflux is by control of nibs at the outlet.

What is claimed is: 
     
       1. A method for controlling the temperature of air efflux from a heated or cooled air outlet to ambient air, comprising: providing a controllable fluidic island oscillator in said air outlet, and   controlling the oscillatory and non-oscillatory conditions of said island oscillator to moderate the mixing of said air flow through said outlet with ambient air and thus modulate said air efflux.   
     
     
       2. The method defined in claim 1 wherein said fluidic oscillator includes nibs at the sides of said outlet, and controlling the directionality of air vector issuing through said outlet during non-oscillatory time of said fluidic oscillatory by venting the space upstream of one of said nibs. 
     
     
       3. The method defined in claim 1 wherein said oscillator is an island oscillator having an island therein and the step of controlling includes translating the position of said island relative to said outlet. 
     
     
       4. A method for controlling the temperature of air efflux from a heated or cooled air outlet, comprising: providing a controllable fluidic oscillator in said air outlet, and   controlling the oscillatory and non-oscillatory conditions of said oscillator, said oscillator being an island oscillator and said controlling the oscillatory and non-oscillatory conditions of said oscillator including the step of supplying high pressure air to a point on said island to terminate formation of Karman vortices thereabout.   
     
     
       5. Apparatus for controlling the temperature of air efflux from a heated or cooled air outlet, comprising: a controllable fluidic island oscillator in said air outlet, and   means for controlling the oscillatory and non-oscillatory conditions of said island oscillator to moderate the mixing of said air efflux with ambient air and thus modulate said air efflux.   
     
     
       6. The invention defined in claim 5 wherein said fluidic oscillator is an island oscillator having nibs at the sides of said outlet, and means for controlling the directionality of air vector issuing through said outlet during non-oscillatory time of said fluidic oscillatory by venting the space upstream of one of said nibs, respectively. 
     
     
       7. The invention defined in claim 5 wherein said oscillator is an island oscillator having an island therein and said means for controlling includes means translating the position of said island relative to said outlet. 
     
     
       8. Apparatus for controlling the temperature of air efflux from a heated or cooled air outlet, comprising: a controllable fluidic oscillator in said air outlet, and means for controlling the oscillatory and non-oscillatory conditions of said oscillator, said oscillator being an island oscillator and said means for controlling including means for supplying high pressure air to a point on said island to terminate oscillation.
